Chainsaws

Never push the equipment beyond its design limits. If it will not
do what you want with reasonable ease and speed assume
you have the wrong tool for the job

Contact your local HSS Hire Shop for advice.

When not in use, store the equipment with the chain bar
cover fitted, somewhere clean, dry and safe from thieves.

Withdraw the guide bar from the cut and release the ON/OFF
trigger.

Wait for the chain to stop, unplug the saw from its power sup­ply, then refit the chain bar cover.

Finally, clean the saw ready for return to your local HSS Hire
Shop.

The top directional cut is made first, bringing the
saw downwards at 60 degrees to a depth 1/4 the
diameter of the trunk. Start high enough up the
trunk to ensure you have enough room for the
bottom directional cut.
The bottom directional cut is made by bringing the
saw up at an angle of 30 degrees to meet the top
cut. A perfect directional cut has an angle opening
of 90 degrees.
Next, the felling cut is made horizontally on the
opposite side at a level slightly higher than the tip of
the directional cut. The cut is made leaving at least
25mm to act as the hinge. When halfway through
the felling cut, insert a pry bar, or drive a wedge,
into the cut to prevent the saw being trapped.
When the cut is complete remove the chainsaw ­turn it off and put it down in a safe place.

When making a final felling cut to a tree, follow the next few
instructions carefully referring to the
illustration for additional guidance.

Cutting Guide

If the guide bar becomes trapped in a cut, release
the ON/OFF switch and unplug the saw from its
power supply before freeing it. Do not lever the bar
free or you will damage the saw.
Make sure you are clear of the saw as it clears the
cut. After finishing a cut, release the ON/OFF switch
before moving on to another branch or tree.
Do not cut through branches that are under tension
unless you have been specially trained.

Squeeze the trigger and bring the saw up to maximum
speed and cut vertically downward or horizontally in
a straight line without forcing the saw through the wood.
If felling a tree, do not cut lower than 10” above soil level
and never use the saw to cut roots (this includes stumps
previously pulled from the ground).
Remember, soil is the chain’s worst enemy and will blunt a
chain in seconds!
To help stop the saw ‘kicking back’ out of control,
always cut with the underside of the guide bar nearest the
saw
body, keeping the front of the
saw body against the wood.
NEVER cut with the tip or top
edge of the guide bar.
Never let the chain touch the
ground, nor any metal or
masonry obstructions. This may
cause ‘kick back’ and will
damage the blade.
If the saw does ‘kick-back’, the
chainsaw’s brake automatically
stops the chain and isolates the motor from the power sup­ply, so, release the ON/OFF
switch immediately.
Check the work to see what the cause of ‘kick back’
was, then take all necessary steps to ensure it
doesn’t happen again. Don't forget to reset
the chain brake

Each HSS chainsaw is fitted with a new chain for

every hire. Check the chain tension after the first 10

minutes use and every 15 - 20 minutes thereafter.

Always switch OFF and wait for the chain to

stop before doing this.

Always wear protective gloves.

To adjust the tension, slacken off the guide bar

mounting nuts, angle the bar upwards, then turn the

tension screw (inside edge of the bar) - clockwise to

tighten the chain - anti-clockwise to loosen it.

At the correct tension, the chain should rotate

freely and be slack enough to be moved by hand.

There should also be 4 guide teeth visible above the
bar when pulled upwards, yet tight enough for them
to stay in contact with the guide bar (see illustration).
Re-tighten the guide bar mounting nuts, doublecheck

the chain tension, then, wearing gloves, move the

chain forward along the guide bar by hand to make

sure it revolves freely.

Make a small cut on the underside of any branch you want
to lop, then cut -down from the top to remove it. Never try

to cut right through a branch from one direction or the

saw will jam in the cut.
